Interlocking panel

ABSTRACT

An interlocking panel, and structures formed therefrom, are described herein. Embodiments of the present invention provide a panel including a protruding end including a receiving member for engaging a complementary engaging member of a first adjacent panel, and a receiving end including two flanges, at least one of the two flanges including an engaging member for engaging a complementary receiving member of a second adjacent panel, one or both of the two flanges configured to flex to allow the complementary receiving member of the second adjacent panel to engage the engaging member.

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to U.S. Provisional Patent Application No. 60/895,939, filed Mar. 20, 2007, entitled “Interlocking Panel,” the entire disclosure of which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

Embodiments of the invention pertain to interlocking panels and structures formed therefrom, and particularly to panels which may be assembled by engaging one another along their lengths for a removably coupled or interlocked engagement.

BACKGROUND

Structures having high flexural strength and rigidity as well as a degree of modifiability in terms of ultimate structure size are sometimes desirable. For example, tractor-trailer trucks may include cargo structures for transporting and/or storing material. Although the size of these structures may be known, it may be desirable to expand or decrease the size of the structure (for example, to accommodate the size of the trailer), or to completely disassemble the structure when not needed. In many cases, it is desirable for such an assembly process to be automated.

U.S. Publication No. 2006/059791 illustrates the use of panels having 1) a member-connecting side having a pivot-receiving slot for rotatably receiving the pivot, and 2) an arcuate wing-receiving slot for receiving the wing during relative rotation of at least one of the first and second members with respect to the other. This construction is inefficient and cumbersome, as it requires the rotating of the panels during assembly. Rotation of such panels makes the panels difficult to assembly quickly, particularly if the assembly process is to be automated.

The description may use perspective-based descriptions such as up/down, back/front, and top/bottom. Such descriptions are merely used to facilitate the discussion and are not intended to restrict the application of embodiments of the present invention.

Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments of the present invention; however, the order of description should not be construed to imply that these operations are order dependent. Moreover, some embodiments may include more or fewer operations than may be described.

The terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may mean that two or more elements are in direct physical or electrical contact. However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other.

The term “interlocking,” along with its derivatives, are used herein. These terms may broadly refer to structures being permanently or temporarily coupled, depending on the application.

Embodiments of the present invention may include panels configured to interlock to form various structures. In various embodiments, the interlocking panels may be suitable for applications including, for example, cargo enclosures for tractor-trailer trucks and similar vehicles. Other applications also may be within the scope of the present invention including storage structures, shipping containers and temporary shelters.

According to various embodiments, the panels may be interlocked by engaging the panels with each another along their lengths by a snap-fit/interlocked engagement. This novel structure allows for simple assembly by pushing one end of a panel into a complementarily configured other end of another panel without the need to rotate one or both of the panels, and generally without the need for special tools or complicated assembly techniques.

FIG. 1 illustrates a cross-sectional view of a panel 100 in accordance with various embodiments of the present invention. Panel 100 includes a protruding end 102 and a receiving end 104. Protruding end 102 includes at least one receiving member 106, and receiving end 104 includes generally parallel flanges 108 including at least one engaging member 110 disposed on facing surfaces of flanges 108.

Panel 100 may be configured to couple to another panel. For coupling, receiving member 106 may be configured to engage a complementary engaging member (similar to engaging member 110) of another panel. Similarly, engaging member 110 may be configured to engage a complementary receiving member (similar to receiving member 106) of yet another panel. In various embodiments, one or both flanges 108 may be configured to flex to allow a complementary receiving member of another panel to engage engaging member 110.

FIGS. 2A and 2B illustrate an exemplary operation for coupling two panels 200 a, 200 b. Similarly to panel 100 illustrated in FIG. 1, panels 200 a, 200 b each include a protruding end 202 a, 202 b and a receiving end 204 a, 204 b. Protruding ends 202 a, 202 b each include at least one receiving member 206 a, 206 b, and receiving ends 204 a, 204 b each include at least one engaging member 210 a, 210 b carried by flanges 208 a, 208 b. In various embodiments, non-coupling ends such as 202 b and 204 a may be of a different configuration for coupling to a different structure (e.g., a door, a frame, etc.).

Panel 200 a may be coupled with panel 200 b by inserting protruding end 202 a of panel 200 a into receiving end 204 b of panel 200 b. As illustrated in FIG. 2A, panel 200 a is inserted into panel 200 b along a direction substantially parallel to flanges 208 b.

As protruding end 202 a is inserted into receiving end 204 b, flanges 208 b may flex to a degree sufficient to allow engaging members 210 b to engage receiving members 206 b. Once the engaging members 210 b engage receiving members 206 a, flanges 208 b may snap back to their non-flexed position to hold panels 200 a, 200 b together, as illustrated in FIG. 2B.

According to various embodiments, the panels may be configured to provide a desired degree of flexural resistance. As illustrated in FIG. 2A and FIG. 2B, for example, panels 200 a, 200 b, rather than being hollow, may include at least one intermediate structure 212 a, 212 b disposed between outer surfaces 214 a, 214 b. Intermediate structure 212 a, 212 b may prevent or resist flexing in a desired direction, and/or collapsing of panels 212 a, 212 b under pressure. In various embodiments, intermediate structure 212 a, 212 b may be oriented perpendicularly to outer surfaces 214 a, 214 b, respectively, for providing the flex-resistance. In some embodiments, a panel may include no such structures, depending on the application. For example, in low-stress applications, strengthening features may not be necessary. Further, in various embodiments, the panels may be filled with a material such as foam to provide additional strength, rigidity, noise reduction, etc.

Any material suitable for the particular application in which panels 200 a, 200 b are enlisted may be used to form panels 200 a, 200 b. For example, any one or more of various metals and their alloys may be appropriate or desirable for an application. Aluminum, for example, may be an appropriate material for a number of applications. In some embodiments, plastic or similar materials may be appropriate.

Panels in accordance with various embodiments of the present invention may be used for forming a variety of structures. For example, interlocked panels may be used for forming enclosures, doors, walls, or the like. In some embodiments, interlocked panels may be suitable for cargo enclosures configured to mount onto a vehicle such as, for example, tractor-trailer trucks, trains, or similar vehicles. Other applications also may be within the scope of the present invention including storage structures and temporary shelters.

FIG. 3A is a front view of an exemplary structure 314. FIG. 3B is a cross-sectional view of the structure of FIG. 3A, taken along the 3B-4B line, and FIG. 3C is a cross-sectional view of the structure of FIG. 3A, taken along the 3C-3C line.

As illustrated, structure 314 is formed from a plurality of interlocked panels 300, coupled as described herein. In various embodiments, panels 300 may be disposed, with respect to the resultant structure, in a generally horizontal, vertical, diagonal, or other orientation, depending on the application.

In some embodiments, one or more trim or edge structures 316 may be coupled to interlocked panels 300 for adapting structure 314 for the particular application. For example, trim structures 316 may include, for example, rail and/or stile elements (for a door, for example), hinges, or the like.

In some embodiments, panels may be further fastened in addition to interlocking. For example, in the embodiment illustrated in FIG. 4A-4C, the panels 400 are fastened at each interconnection point by fasteners 424. This embodiment may be useful for applications in which the panels will not be disassembled for some period of time. This embodiment may also be useful if additional structural fortification is desired.

Fasteners 424 may be used for fastening panels 400 together and/or for fastening one or more panels 400 to various trim structures 416. As described herein, trim structures 416 may be coupled to interlocked panels 400 for adapting structure 414 for the particular application, and may include, for example, rail and/or stile elements (for a door, for example), hinges, or the like.

Various fasteners 424 may be suitable for fastening panels 400 together. In various embodiments, suitable fasteners may include rivets. Other fasteners may be similarly suitable. For example, in some embodiments, any one or more of screws, bolts, clips, and/or pins may be used for fastening panels 400 together. In still further embodiments, panels 400 may be, welded, glued, or soldered together in addition to or instead of using mechanical fasteners.

An exemplary structure 514 formed using a plurality of panels is illustrated in FIG. 5A. FIG. 5B illustrates a front perspective view of structure 514, and FIG. 5C illustrates a cross-sectional top view of structure 514. The illustrated structure 514 is a pair of doors 518 a, 518 b, each door including a plurality of interlocked panels 500 and various trim structures including rails/stiles 522, and carrying hinges 520.

As illustrated in FIG. 5C, hinges 520 are recess-mounted to align with the outer surface of doors 518 a, 518 b. This embodiment may be particularly useful for applications wherein a substantially smooth outer surface is desired. In some embodiments, for example, ease in cleaning the outer surfaces of doors 518 a, 518 b may be necessary.

FIG. 5C also illustrates a sealing strip 521 disposed on door 518 b. Sealing strip 521 may abut door 518 b when doors 518 a, 518 b are closed. Although sealing strip 521 is illustrated in its unflexed configuration, sealing strip 521 would normally be flexed to abut the edge of door 518 b to provide the desired contact between doors 518 a, 518 b.

FIG. 6A and FIG. 6B are front views of another structure 614 formed from a plurality of interlocked panels 600 in accordance with various embodiments of the present invention. The illustrated structure 614 is a pair of doors 618 a, 618 b, each door including a plurality of interlocked panels 600 and various trim structures including rails/stiles 622, and carrying hinges 620.

FIG. 6A and FIG. 6B also illustrate a locking system 623 for locking doors 618 a, 618 b to a carrying structure 629. Carrying structure 629 may comprise any structure onto which doors 618 a, 618 b may be mounted. For example, carrying structure 629 may comprise a cargo enclosure, a storage structure, a shipping container, a shelter structure, a vehicle, etc.

Locking system 623 includes a locking bar 625 (illustrated in phantom), which may be disposed on a rear/inner surface or within the door, depending on the application. Accordingly, locking bar 625 may effectively be “invisible” from an exterior side of doors 618 a, 618 b. The placement of locking bar 625 on a surface other than an exterior surface of doors 618 a, 618 b may be desirable for providing a substantially smooth outer surface of doors 618 a, 618 b, security reasons (e.g., to prevent tampering with locking bar 625), and/or aesthetic reasons.

Locking system 623 may allow for locking and unlocking of doors 618 a, 618 b by way of a latch 626. In various embodiments, unlatching of latch 626 may cause locking bar 625 to rotate and either raise or lower (depending on whether latching or unlatching, respectively) for engaging or disengaging a receiver 627.

Structure 614 may include any number of locking systems 623, depending on the application. For example, in the illustrated embodiment, each of doors 618 a and 618 b include two locking systems 623. In various other embodiments, however, a door may include just one locking system 623 or may instead have none.

Other locking systems may be similarly suitable for locking doors or panels within the scope of the present disclosure. As illustrated in FIG. 7, for example, a structure 714 includes doors 718 a, 718 b, and locking bars 725 a, 725 b on a rear surface door 718 b. An actuator 728 may be configured to cause locking bar 725 a to raise or lower, and resultantly, engage or disengage a receiver (not illustrated), respectively. Similarly, actuator 728 may be configured to cause locking bar 725 b to raise or lower, and resultantly, disengage or engage a receiver (not illustrated), respectively.
